Other income

I did enter manually my interests earns from savings as "other income " I did introduce the amount wrongly, as I should have taken off the £1000 tax free allowance. I don't know how to amend this, as i found it confusing. Could someone help please? Thanks in advance

Hi rosaaramburu2009,
There is a box specifically for taxed or untaxed interest.
You enter you interest in the appropriate box and Self Assessment will apply the tax free threshold for you.
If you have a government gateway user ID and password, you can log into or register for a personal tax account:
Personal tax account: sign in or set up
Where you can log in to your tax return and amend it.
If you send in a paper tax return, you can either submit and amended paper tax return or a letter advising which boxes need to be amended.
Thank you.
